Benefits of technology

[0007] According to one aspect of the present invention, a new and improved motorcycle tire is provided which comprises a pair of beads, a carcass extending between the beads, a tread disposed outwardly of the carcass where the tread has tread edges. The tire further comprises a pair of sidewalls extending from the tread edges to the respective beads. The tread further includes a first rubber composition having a working temperature and a second rubber composition having a working temperature, wherein the first rubber composition reaches its working temperature faster than the second rubber composition reaches its working temperature. The first rubber composition and the second rubber composition are adapted to contact an associated underlying surface. The combination of the first rubber composition and the second rubber composition is intended to provide more even wear across the tire tread in order to increase the life of a tire and provide better tire performance.

Problems solved by technology

While the grip of a high performance tire is high, the tire tread wears quickly.
This irregular wear could change the ride behavior of the motorcycle tire.
However, uneven wear, or the use of a harder rubber during high speed drives, may have an effect on handling, especially during acceleration, braking, and steering around curves.

Embodiment Construction

[0026] Referring now to the drawings wherein the showings are for purposes of illustrating a preferred embodiment of the invention only and not for purposes of limiting the same, FIGURES 1-7 show the present invention. With reference to FIG. 1, a motorcycle tire 10 well known in the art is shown. By way of example, the following description provides details of general tire components. There is shown a motorcycle tire 10, which is a toroidal-shaped composite structure which is provided with a pair of circular substantially inextensible beads 12 for mounting of the tire on a rim. The tire 10 has an equatorial plane EP, which is the plane perpendicular to the tire's axis of rotation and passing through the center of its tread 18. A pair of sidewalls 14 extends from the beads 12 respectively to a crown portion 16, which extends circumferentially about the tire 10. Tread 18 for engaging the ground is provided on the outer periphery of the crown portion 16. A carcass of two or more plies ...

Description

I. BACKGROUND OF THE INVENTION [0001] A. Field of Invention [0002] This invention pertains to the art of methods and apparatuses for a motorcycle tire, and more specifically, a motorcycle tire having tread formed from a combination of soft, medium, and hard rubbers to provide for more even wear of the tire tread. [0003] B. Description of the Related Art [0004] Treads of rubber tires are often prepared of a cap base construction in which the outer portion of the tread is the cap and the underlying part of the tread between the tread cap and the supporting tire carcass, is its base. The cap portion is usually designed to be ground contacting and, thus, have associated properties. The base portion generally overlays the tire carcass and is usually designed to support the cap, therefore, not to be ground contacting. Such cap base constructions are well known to those skilled in the art. [0005] It is known in the art for tread of motorcycle tires to be made from the same rubber compositi...
